由于激光准确的波长,可以精确确定其在颜色匹配曲线上的数值。基于激光的这一特性,提出了一种新的光色性能的测量方法和系统。该系统充分利用了激光显示的优势,色度探头采用双通道反馈放大回路切换,并在PC中建立数据库存储数据,它配有GUI界面,极大地方便了不同用户的使用。实验结果证明该系统可以低成本实现光通量、照度均匀度、色度均匀度、对比度等主要光色性能的精确测试。
Due to the accurate wavelength of the laser, its value on the color matching curve can be precisely determined. Based on this characteristic of laser, a new measuring method and system of light color performance is proposed. The system takes full advantage of the advantages of the laser display, the chromaticity probe using dual-channel feedback amplifier loop to switch and create a database stored in the PC data, it is equipped with a GUI interface, which greatly facilitates the use of different users. The experimental results show that the system can achieve the accurate test of the main light color performance such as luminous flux, illumination uniformity, color uniformity and contrast at low cost.
